Title: Pitch control of aircraft
IPC: G05D1/06
Filed: 1956-09-10
Abstract: 807,111. Automatic control systems for aircraft. BENDIX AVIATION CORPORATION. Sept. 10, 1956 [Sept. 22, 1955], No.27637/56. Class 38 (4). In an aircraft control system the elevators are controlled by a signal dependent on rate of change of altitude combined with a decaying signal which is initially dependent on change of pitch. As shown a signal dependent on altitude is developed in a winding 26 of an inductive pick-off 24 associated with an aneroid 20. This signal is applied through an amplifier 27 to control an induction motor 29 which adjusts pick-off 24 to give zero output. An inductive device 41 and an inductive generator 33, both driven by motor 29, thus respectively produce signals, representative of altitude and rate of change of altitude, which are applied through an isolation amplifier 54 to an amplifier 80 controlling a servomotor 70 adjusting the elevators to maintain constant altitude. A signal dependent on pitch altitude is also developed by an inductive pick-off 87 associatd with a gyro vertical 85 and applied through an inductive device 90 to amplifier 80. This signal is however gradually reduced to zero by a motor 97 which is controlled through an amplifier 95 by the signal from inductive device 90. The speed of motor 97 is made dependent on the signal from inductive device 90 by virtue of rate feedback from a tachometer generator 99. A signal dependent on rate of change of pitch, developed by an inductive pick-off 60 associated with a pitch rate gyro 64, is applied to amplifier 80. Positional and rate follow-up signals, developed by an inductive device 69 and inductive generator 67 respectively, are also applied to amplifier 80. Climb or dive is effected by (a) operating a push button 40 to open switch 45 and thereby deenergizing a clutch 44 so that pick-up 41 no longer responds to altitude changes and (b) moving a lever 39 to set the desired rate of climb or dive by adjusting an inductive device 37 the output of which is applied to amplifier 80.

Void [Published under Sect. 91 of the Acts]. Class 40 (iii).] A photo-electric device comprises an electrode, consisting wholly or in part of a photo-electric substance, separated from a second electrode by a layer of one or more insulating or semi-conducting substances and a second layer constituted by a fluorescent material, with the electrodes and the separating layers in superposed relation. An evacuated glass vessel 1 is sealed with a ground glass plate 2 on which is formed a platinum electrode 3 by volatilizing a platinum wire, and a fluorescent layer 4, which may be formed by the method described in Specification 380,256, [Group XX], is deposited on the conducting electrode 3. The fluorescent layer is coated with a layer 5 of an insulating or semi-conducting substance on which is formed a layer 6 of the photoelectric substance which forms one electrode of the system and has a contact member formed by a thin layer 7 of platinum. The contact member for the photo-electric electrode may be of the form described in Specification 379,788. A lens 11 concentrates light from an object on to the electrode 6 which by electron emission excites the layer 4 to fluorescence. The fluorescent rays may be utilized to augment the photo-electric effect of the device if the electrode 6 is sensitive to fluorescence, or to impinge on the photo-electric electrode of a second device mounted within or without the wall 1 of the first photo-electric device. The cell may be employed to obtain a photographic exposure of a faintly luminous image by allowing the fluorescent rays emitted from various parts of the layer 4 to impinge on a photographic plate 12 which is arranged to be highly sensitive to the fluorescent rays emitted. The photoelectric electrode may consist of barium, cµsium or potassium, whilst the insulating or semi-conducting substance may be barium oxide, zirconium oxide, calcium fluoride, silver iodide or copper oxide. Examples of fluorescent substances include zinc sulphide, scheelite (calcium tungstate) and barium platinocyanide. If the fluorescent substance emits ultra-violet radiation which is to be directed to a second photoelectric device or to a sensitized photographic plate, the conducting electrode 3 may be of silver or may consist of a thin film of silver deposited on a layer of quartz. Specifications 378,451 and 378,457 also are referred to.
